Although the presentation is not viewable online, it is downloadable. The reason it is not able to be previewed online is because Google sets a certain limit to file sizes--meaning our presentation is a large file due to the embedded video clips!--However, this allows us to still embed the file. We are able to download and view the presentation instead.
For the Google Website version of this presentation, we made a more simple version of our actual presentation in order for the website to preview the slides. The Google Slides version of our presentation is NOT the actual presentation format itself--it is a merely for being able to view the presentation online. To view our actual presentation to the left, it must be downloaded.
